Can't Change Print Speed Over USB

[CraigyD01 0]

Hi - I'm using Cura 4.6.2 (yes I know v4.7 is out there - I'll download shortly) on my iMac with direct USB connection to my Creatlity CR10s Pro v2. If I used the conventional SD Card path, I'd be able to amend my print speed on the CR10, but using Cura over USB, I can't change it from the default to another value. Anyoine come across this and a method I can use to adjust print speeds during a print?

I don't have an answer for your specific question, but printing over USB is old and not recommended, so just use the SD card and you are much safer. The functionality is included in Cura for some backward compatibility, but AFAIK not actively developed anymore.

The USB side of Cura isn't supported by Ultimaker anymore.  None of their printers require it so it's legacy software at this point.  If the side of Cura that is busy sending Gcode doesn't allow for interruption then you will need to try Pronterface/Printrun or maybe Octoprint.  Pronterface allows you to see the responses from the printer as well as send codes.  You can also write your own macro scripts and send them to the printer.
